However, this assumption is too simplistic in the most real-life situations due to a natural phenomenon in a production process. From this it is deduced that the system produces non-perfects items which can be classified into four groups of perfect, imperfect, reworkable defective and non-reworkable defective items. In this paper, compared with classic model, a new integrated imperfect quality economic production quantity problem is proposed where demand can be determined as a power function of selling price, advertising intensity, and customer services volume. Furthermore, as novelty way the unit cost is defined as a cubic function of outputs which is similar to real world. Also, a geometric programming modeling procedure is employed to formulate the problem. Finally, a numerical example is illustrated to study and analysis the behavior and application of the model.}, keywords = {Geometric programming,Inventory,Comprehensive demand function,Cubic production cost function,Non-perfect production process}, url = {https://www.jise.ir/article_43331.html}, eprint = {https://www.jise.ir/article_43331_3da8dce3869a5b98ac36ff5d4bd958d2.pdf} }
